Sorry, I meant: do Lutra & other otters have rel.large brains?
I'm esp. interested in Enhydra vs other otters.

A DHA rich diet never insures a larger brain. At best, it can only ensure a brain as large as genetics will allow.

Our human brains are dependent upon DHA. We require a lot of it. This
doesn't mean that exposure to DHA results in large brains. It requires
that our ancestors evolved under conditions which were so rich in DHA
that we could be dependent upon it and STILL thrive.

Brain size is an excellent test for human evolution BECAUSE we are so
dependent upon DHA.

If we find a population on the coast, exploiting marine resources, and
another landlocked, the coastal population should have measurably
larger brains as a group.

So if we hunt for fossils where Sundaland used to be, and compare
them to landlocked African fossils, the Sundaland finds should
display measurably larger brains... BECAUSE of their diets.

It's not magic. Diet is know to affect humans physically. MODERN
humans are supposedly not getting enough DHA, even though we
are supposedly much better at synthesizing DHA from ALA than
our ancestors were... we're still bad at it.

Again, the issue isn't that exposure to DHA results in huge brains.
The issue is that humans are dependent upon DHA, and we just
plain couldn't be unless we evolved under circumstances where it
was abundant.

See supplementary Data 2 in:

Otters, in particular Enhydra en Lutra, are not exceptionally
encephalized among mustelids.

Hey, mongoloid; You ONCE AGAIN display your stupidity.

You're disarticulated. You can't form coherent thoughts, much less
models. You think if you can attack a piece then the whole model
vanishes. And you think this because you're an idiot.

Humans evolved under circumstances in which DHA was available
in abundance. Period.

Our dependence on DHA proves we evolved under circumstances
where DHA was available in abundance.

Turn back the clock, human ancestors were LESS capable of
synthesizing DHA, not more so. Relying entirely on synthesizing
DHA from ALA is considered inadequate TODAY, it was WORSE
in the past, before adaptions for improved synthesis. So our
ancestors were MORE not less dependent upon marine resources.

But it's just one piece of the puzzle, one part of a large, coherent
model that you constantly remind us you are unable to fathom.

The DHA matches up with the Aquatic Ape. Aquatic Ape matches
exactly with Coastal Dispersal. Coastal Dispersal explains HOW
and WHY our ancestors spread across continents. It matches the
evidence of different populations (multiregionalism), explains why
that is, explains how they remained one species.

It's an entire model. And you've got nothing except some confused, disarticulated thoughts that you were trained to regurgitate.

At least 8 *independent* scientific facts show that Pleistocene archaic Homo were semi-aquatic:
• Archaic Homo's atypical tooth-wear was caused by "sand and oral processing of marine mollusks" Towle cs 2022 doi 10.1002/ajpa.24500.
• H.erectus s.s. fossilized typically (always?) in coastal sediments, e.g. Mojokerto amid barnacles & corals, Trinil amid Pseudodon & Elongaria, Sangiran-17 in "brackish marsh near the coast".
• Stephen Munro discovered sea-shell engravings made by H.erectus (Joordens cs 2015 Nature 518:228–231).
• Ear exostoses (H.erectus & H.neand.) develop after years of cold(er) water irrigation.
• Pachyosteosclerosis is typically & exclusively seen in slow+shallow-diving tetrapods (de Buffrénil cs 2010 J.Mamm.Evol.17:101–120), e.g. erectus' parietal bone is 2x as thick as in gorillas.
• Brain enlargement++ (e.g. Odontocetes, Pinnipedia) is facilitated by sea-food, e.g. DHA docosahexaenoic acid in shellfish etc.
• Homo’s stone tool use & manual dexterity is typical for molluscivores: sea-otters etc.
• Pleistocene Homo even colonized overseas islands (Flores & later even Luzon), google “coastal dispersal Pleistocene Homo”.

"When compared with an average mammal of similar body size, pinnipeds
(seals, sea lions, fur seals, and walruses) have encephalization
quotients similar to those of terrestrial carnivores. Odontocete
cetaceans (toothed whales), with the exception of the sperm whale
(Physeter catodon), have relative brain sizes larger than expected,
similar to the anthropoid primates. Sirenians (dugongs and manatees),
the sperm whale, and the mysticete cetaceans (baleen whales) all have
relative brain sizes smaller than the mammalian average and similar to
the large ungulates."

So, if odontocete cetaceans have EQs similar to anthropoid primates,
how did the latter grow such relatively large brains without seafood?

Thanks a lot, my boy, yes, most aquatic mammals (generally larger body sizes than terrestrial mammals) have larger brains than equally large terrestrial mammals, but nobody ever said (semi)aquaticism explains everything.
Is it a coincidence that mammals that recently evolved from (semi)aquatic to terrestrial have unexpectedly-large brains? e.g. neandertals & elephants? is this why Hn has larger brains than He & Hs? Hn>Hs>>He>>apes-apiths.

Hard to find any credible science in the present hellscape, now
that everything is propaganda, but...

https://www.themarysue.com/cold-climates-bigger-brains/

Oh, TONS of cites claiming Gwobull Warbling is shrinking brains,
but, like I said, that's all propaganda. However, I have long hear,
even if i never expressed much interest in, the claim that bigger
brains correlate with colder climates.

In truth, I have no idea.

There is proof, I won't even say "Evidence," that some Neanderthals
exploiting the sea rather extensively.

And during events like Toba, they pretty much had to. Life inland
would have gotten pretty rough.

I used to think that it was a different solution to the same problem:

Neanderthals got smarter by building bigger brains, other populations
built better brains... fit the same "Smarts" into a smaller space. AND
THEN when the larger brains met with the smarter brains, we got
both: Bigger brains that were also smarter per square inch.

But that was just a pet theory of mine. Never really looked into it.

And, again, I can recall many claims, over the years, that colder climates spawned bigger brains.

What the FUCK is wrong with you?

School's out, child. You don't win any points by regurgitating a
reading verbatim. From the day they gave you that GED it was
all about APPLYING knowledge. No, no what you learned but
what you did with it...

Despite all your many, many, many, many, many, many failings,
humans require DHA and we require a lot of it. We're not great
at synthesizing it NOW, and we're better at it now than our
ancestors were in the distant past. So we evolved under
circumstances where this DHA was plentiful.

DHA = Aquatic Ape

Coastal Dispersal = Aquatic Ape

Good luck trying to grasp a word of this!

It doesn't matter what ottors or mice or bullfrogs need or

large brain, it ensures a brain just as large as genetics will
allow. Humans were under a great deal of selective pressure
to be problem solvers -- get smart.

Dolphins can never match us, no matter what, not without
evolving to leave the oceans and walk on dry land. One
rather obvious reason for this is their lack of useful hands,
opposable thumbs. Another is that fire doesn't work so
well under the water. Oh, there are molten rocks under the
sea... for a little while. Until they cool. But if a dolphin got
close enough to try and smelt iron it would be cooked
before it had its first attempt.

And, again, you are an idiot.

this is no coincidence:

•Stephen Munro: sea-shell engravings made by H.erectus, Joordens cs 2015 Nature 518:228–231 https://pubmed.ncbi.nlm.nih.gov/25470048/
•Archaic Homo's atypical tooth-wear is caused by "sand & oral processing of marine mollusks", Towle cs 2022 https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24500
•Ear exostoses (H.erectus & H.neand.) develop after years of cold(er) water irrigation. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696936/

IOW, one must be stupid stupid stupid to deny that archaic Homo had a lot of aquatic foods in their diet.
